Magnetization reversal in nanotriangles fabricated by nanosphere lithography

Magnetization reversal in nanotriangles fabricated by nanosphere lithography

We report on the magnetization reversal behavior of sub 100-nm triangular shaped Ni80Fe20 dot array fabricated by nanosphere lithography. Hysteresis loops measured by magneto-optical Kerr effect magnetometry are classified into single and double-switched loops in 45 nm, 80 nm and 100 nm triangular n...
